Reports <code>if</code> statements in which common parts can be extracted from the branches.
<p>These common parts are independent from the condition and make <code>if</code> statements harder to understand.</p>
<p>Example:</p>
<pre><code>
  if (x &gt; 12) {
    doSomethingBefore();
    doSomethingDifferent1();
    doSomethingAfter();
  } else {
    doSomethingBefore();
    doSomethingDifferent2();
    doSomethingAfter();
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  doSomethingBefore();
  if (x &gt; 12) {
    doSomethingDifferent1();
  } else {
    doSomethingDifferent2();
  }
  doSomethingAfter();
</code></pre>
